G'day  Phil,

here are some of my arguments in support for enabling the  stepping
attenuator in Hermes:

* some premium receivers provide  0,10,20 and 30dB attenuation in the
receive path. Switching between 0dB and  20dB is like driving a Ferrari
that only has first and last gear.

*  using Hermes as a measurement receiver. 

* The step attenuator is  already there, make it accessible and let
application developers and users  decide whether or not to take advantage
of this option.
